Measuring the spatial extent of individual localized photonic states

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Marko Spasenovic, Daryl M. Beggs, Philippe Lalanne, Thomas F. Krauss, L. | Summary: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with […]

Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment

Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken, RenĂ© van Roij, Marjolein Dijkstra | Summary: The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The specific case of the restricted primitive model […]

Opportunities and limitations of transition voltage spectroscopy: a theoretical analysis

Kavli Affiliate: Joseph M. Thijssen | First 5 Authors: Fatemeh Mirjani, Joseph M. Thijssen, Sense Jan van der Molen, , | Summary: In molecular charge transport, transition voltage spectroscopy (TVS) holds the promise that molecular energy levels can be explored at bias voltages lower than required for resonant tunneling. We investigate the theoretical basis of […]

Digital Plasmonics

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Bergin Gjonaj, Jochen Aulbach, Patrick M. Johnson, Allard P. Mosk, Kobus Kuipers | Summary: The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound to a metal dielectric interface, tightly confine […]

DFT-based many-body analysis of electron transport through molecules

Kavli Affiliate: Joseph M. Thijssen | First 5 Authors: Fatemeh Mirjani, Joseph M. Thijssen, , , | Summary: We present a method which uses density functional theory (DFT) to treat transport through a single molecule connected to two conducting leads for the weak and intermediate coupling. This case is not accessible to standard non-equilibrium Green’s […]

Cross-link governed dynamics of biopolymer networks

Kavli Affiliate: Martin Depken | First 5 Authors: Chase P. Broedersz, Martin Depken, Norman Y. Yao, Martin R. Pollak, David A. Weitz | Summary: Cytoskeletal networks of biopolymers are cross-linked by a variety of proteins. Experiments have shown that dynamic cross-linking with physiological linker proteins leads to complex stress relaxation and enables network flow at […]

Three-dimensional negative index of refraction at optical frequencies by coupling plasmonic waveguides

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Ewold Verhagen, RenĂ© de Waele, L., Kuipers, Albert Polman | Summary: We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs […]
